Specification of Letters Patent.

Patented ltltay 1t?, 1914.

Application filed October 29, 1918. Serial No. 758,11l.

To @ZZ eti/tom, it may concernv Be it known that l., HENRY NEUMAN, a citizen oit the United States, residing at An derson, in the county oit Madison and State of Indiana, have invented new and usei'ul improvements in Gearing, ot which the following is a specilication,

The present invention rela tes to operating y mechanism chiefly tor washing machines but it is obvious that such mechanism may be readily adapted to machines oit analogous nature.

rlhe invention provides a reciprocating rack7 a lfly wheel having connection with such rack and connecting means between the rack and the part to be driven, the ily wheel being driven continuously in the saine direction whereas the rach bar has a reciinoeatingl movement imparted thereto and in turn actuales the driven partl by means ci an oscillatory movement.

The invention consists ot the novel features, details of construction and combination of parts, which hereinafter will be more particularly set forth, illustrated in the accompanying drawings, and pointed ont in the appended claims.

Referring to the drawings, forming a part et the specification, Figure 1 is a side view oi an operating mechanism embodying' the invention showing the same in connection with a washingl machine. Fig. 2 is a section on the line a-U ot Fig. 1. llig. 3 is a horizontal section on the line g/-y/ ot Fig. 1. Fig. l is a detail view oit the rack. Fig. 5 .is a detail view ot a modification in which a rotary movement is imparted direct-ly to the ily wheel and the latter in turn imparting a reciprocating movement to the rack.

Corresponding and like parts are re lierred to in the following description, and indicated in all of the views ot the drawings, by the saine reference characters.

llhe numeral 1 designates a tub which is adapted to receive the .mechanism such as the rubber or other agitator when the mechanism is adapted for operating the washing machine. 1li vertical shaft 2 passes centrally through the bottom of the tub and is provided at its lover end with a mutilated pinion 3 which is arranged to cooperate with a rack 4t having a toothed portion 5 arranged to mesh with the teeth of the pinion 3. A plate 6 is secured to the bottom et the tub and is :formed with a plurality of lugs 7 of hook form which engage and snpport the raclr 4. and direct such rack in its reciprocating movements. Upon imparting a reeiproeating movement to the rack zfl- 'the pinion 3 is oscillated and such movement is transmitted by means of the shail't 2 to the part to be operated. For imparting a re* Ciprocating movement to the rack it a lever S is located at one side oit the tub and is pivoted to a bracket 9. A, link 10 connects the lower end of the lever S with the ra el; 4t. A roller 11 is arranged to engage an edge ot the rack l and materially lessens the liriction incid-ent to the operation ot such rack. A tly wheel 12 is located below the tub 1 and in a plane parallel with 'the bottom thereof. The ily wheel is operated by means of a bearing 13 which is connected by arms let with the legs 15 upon which the tub is mounted. The ily wheel 12 is provided with a wrist pin 1G which is adapted to engage a slotted portion 17 depending from the rack fl, the slotted portion 17 extending tansversely at an angle of about GO so as to prevent the wrist pin trom stopping` on a dead center. rlhe parts are so proportioned and arranged that a reciproeatingmovement et the rack imparts a continuons rotary movement to the fly wheel and an oscillatory movement to the pinion 3 and part to be driven.

ln the modification shown in the Fig. 5 the lever 8 and linl; 10 are dispensed with and the ily wheel 12 has a shaft which extends through the bearing 18 and is provided at its lower end with a beveled gear 17 which is in mesh with a beveled gear 18 secured to the inner end of a horizontal shat't 19 mounted in suitable bearings and provided at its outer end with a pulley Q0 to which power is applied in any manner by neans of a drive beltln this construeu tion the power is applied to the ily wheel and the latter by reason ot its connect-ion with the rack imparts a reciprocating movement thereto.

From the :foregoing description taken in connection with the accompanying drawings, the advantages of the construction and oit the method ot operation will be readily apparent to those skilled in the art to which the invention appertains, and while l have described the principle ot operation ot the invention, together with the device which I now consider to be the best embodiment thereof, l desire to have it understood that,

the device shown is merely illustrative, and that such changes may be made when desired as are Within the scope of the claims appended hereto.

Having thus described the invention what is claimed as new, is

1. In operating mechanism of the character specitied the combination of a rack having a toothed portion and a transverse slotted portion, a pinion having its teeth in mesh With the toothed portion or" the rack and adapted to receive an oscillatory movement and a fly wheel having a Wrist pin in engagement With the transversely slotted portion ot the rack, the parts being arranged to admit of the y Wheel receiving a continuous rotary movement and the pinion an oscillatory movement.

2. In operating mechanism of the character specified, the combination of a rack having a toothed portion and a transverse slot-ted portion, the slot extending at an angle at approximately 60, a pinion having its teeth in mesh With the toothed portion of the rack and a fly Wheel having a Wrist pin entering the transversely slotted portion of the rack.

3. In operating mechanism of the character specified the combination of a plate formed with hook shaped lugs, a rack mounted in such lugs and adapted to have a reciprocating movement imparted thereto, said rack having a. toothed portionand a transversely slot-ted portion, a pinion having its teeth in mesh with the toothed portions ot t-he rack and a fly Wheel having a Wrist pin arranged to operate in the transversely slotted portions of the rack.

In testimony whereof I aiiX my signature in presence of tvvo Witnesses.

HENRY NEUMAN.
